摘　　要：输电线路垂向落差大、热风易聚集、空气对流频发等因素,是造成输电线路雷击频发的主要因素。在对输电线路进行雷电防护的过程中,可以采取如下措施:加强架空线的绝缘水平、接地线路设置、避雷设置等绝缘保护;采用其他的方法进行防雷保护,例如降低线路保护的角度,安装氧化锌避雷器等。The main factors such as large vertical drop of transmission lines,easy accumulation of hot air,and frequent air convection are the main factors causing frequent lightning strikes in transmission lines.In the process of lightning protection of transmission lines,the following mea⁃sures can be taken:strengthen the insulation level of overhead lines,grounding line settings,lightning protection settings and other insulation protection;Other methods are used for light⁃ning protection,such as reducing the angle of line protection and installing zinc oxide arresters.
